HENRY DE ZAVALA, OF BROOKLYN, NEW YORK.

METALLIC RAILWAY-TIE AND FASTENING.

SPECIFICATION forming part of Letters Patent No. 257,437, dated May 2,1882.

Application filed March 13, 1892. (No model.)

T 0 all whom it may concern:

Be it known that I, HENRY DE ZAVALA, a citizen of the United States,residing at the city of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Iron orMetallic Railroad Gross-Ties and Means of Securing ltails to the Same,of which the following is a specification, reference being had therein"to the accompanying drawings, in which-- Figure 1 shows a perspectiveView of my invention, all the parts being in position; Fig.

2, a perspective view of a section of the tieand rail; Fig. 3, aperspective view of a spacingpiece to keep the ties at proper distancesfrom each other; and Fig.4, a longitudinal section of that part of thetie which is under the rail, showing the mode of clamping the rail tothe tie.

Like letters refer to the same parts in all the figures.

This invention relates to metallic cross-ties, made of wrought-iron,steel, or other metallic plates,having one or more longitudinalcorrugations, so as to give elasticity to the tie; audit consists,first, in forming the'scat in the upper crest of each tie or corrugationby pressing, stamping, or hammering, leaving intact the connection ofthe seat with the body of the tie at the side of the seat; second, inthe combination, with a corrugated tie, such as indicated, of a devicefor fastening the rail to the tie, composed of a double-headed bolt witha nut and washer at each end; and, third, of means for spacing the tiesand keeping them in a fixed position in relation to each other, the sameconsisting of a metal band or strip, with ears punched up, by which thecross-ties can be firmly held at whatever distance may be desired, andat the same time act as clamps to prevent the corrugation in the tiesfrom being'pressed down by the weight of passing trains.

The following is a description which will more fully define my inventionand enable others to construct and use the same.

In the drawings, A shows a single corrugation of a cross-tie. This maybe either v shaped', as shown, or U-shaped. Several corrugations orfolds maybe madein asingle plate, or only a single fold, with flanges gg to rest upon the road-bed.

B is the ordinary T-rail. The seat for the rail is shown at h, Fig.2,and is formed on the crest of the corrugation by pressing or stampbig,so as to exactly fit the bottom of the rail. The form of this seat isshown in Figs. 2 and and 4. The double-headed bolt D is formed as shownin Fig. 4, the body lying directly under the rail and the thread endspassing up through the tie, as shown in Fig. 4, the nutsf firmlypressing the washers d against the flange of the rail and the outside ofthe seat, so as to hold the rail firmly in place. For the purpose ofkeeping the ties at a proper distance from each other a metal plate, 0,is provided wit-h punchedupears m, between which the ties are secured byslipping them in and then hammering'down the ears. The ends of thesebands or plates 0 may be turned over the last flange, as shown at c. Thedouble-headed boltl) may be in crosssection either round, square, or anyother suitable shape. The metal of all the parts may be protectedagainst corrosion by anysuitable-meaus-suchasgalvanizing,painting, orother coating.

I do not claim broadly a corrugated metal cross-tieformed of cithcrsingle or multiple corrugations.

The main advantages of my invention are, first, cheapness ofmanufacture, since the seat is stamped or formed by the machinery of therolling-mill; second, ease of laying the track, since all that isrequired is to place the donble-headed bolt in position and the washerand not put on on one side, no-skilled labor being necessary. The railis then put in place on the seat and the other washer and not put on,thus completely locking the rail to the tie; but I do not confine myselfto this method of locking the rail to the tie, as single bolts may beused on each side, if desired, or any equivalent substituted in theplace of the double-headed bolt.

The spacing piece, bar, or plate has the ears punched up at any suitabledistances, as may be required by the wants of the road.

The ordinary fish-plate may be applied to the rails in any ordinary orsuitable manner, and the nuts may beheld by any suitable lock.

Having thus described my invention. what 1 claim, and desire to secureby Letters Patent of the United States, is-

1. A wrought-metal corrugated tie having flattened rail-seats connectedat the sides with ICC the body of the tie and formed by stamping;

. therefor.

3. The clamping-plate 0, having ears m, in

combination with two or more ties, so'ns to space and hold in positionthe said ties, as described.

In testimony whereof I affix my sign iture in presence oftwo witnesses.
